did your doctor tell you that finasteride/dutasteride is a testosterone blocker? it is not, you were lied to, they do virtually nothing to block testosterone.
I'm sorry that this is so common, if you're using Folx (or an equivalent) they all have some kind of "request a new provider" (say this phrase to the customer service representative) process. I know that starting with a new person is hard, but this is a huge red flag. I want you to have someone that doesn't make you read tumblr posts and evaluate the color of their flag.
the short explanation is that those drugs lower your levels of dihydrotestosterone. your doctor thinks that, since DHT is (genuinely true, deeply oversimplified) responsible for a lot of masculinization, blocking DHT will be enough.
the primary problem here is that your doctor is trying to alleviate your gender dysphoria, not help you more closely resemble the woman you want to be.
the secondary problem is that your doctor thinks medicine is a solved science. the longer explanation is that 5-alpha reductase inhibitors are poorly-understood despite the fact that they're the most common form of gender-affirming medication prescribed to cis people.
how much research do you think exists on their efficacy for trans women? yep.
your estrogen and testosterone levels matter. it's not as simple as "more E is good, less T is also good", but if your doctor made you feel like the numbers don't matter and you should let them worry about it? you need a new doctor.
I won't describe the different ways I've felt at different estrogen/testosterone levels, but I can. the difference is large. will your doctor let you find out for yourself?
if not: they work for you. you pay them. fire your doctor
